Python scripting - append frame directly to video
By default blender don't allow to animate in editmode(i.e keyframing vertices properties). So to over come this problem you need to enable AnimAll addon at &quot;preference-&gt;addon -&gt; AnimAll&quot;.
This creates a new tab in right side panel of &quot;3d port view&quot;. Go-to this panel unmark select only check box and Mark points check box.
Hope this help you.
